Eric Ries
Creator of the Lean Startup methodology who redefined the scientific method of entrepreneurship with the Build-Measure-Learn cycle
Eric Ries (born 1978) is an American entrepreneur, author, and speaker, and the creator of the Lean Startup methodology. He combined Toyota's lean production thinking with agile development methods to propose a startup framework centered on MVP (Minimum Viable Product) and the Build-Measure-Learn cycle, fundamentally changing how startups develop products and validate business assumptions. His 2011 book The Lean Startup became one of the world's bestselling entrepreneurship methodology books, translated into over 30 languages and influencing millions of entrepreneurs worldwide. Ries later extended the Lean Startup methodology to innovation management in large enterprises and founded the Long-Term Stock Exchange (LTSE), attempting to promote corporate long-termism at the capital market level.
Methodologies
- Build-Measure-Learn Cycle Implementation Guide - Design every product iteration as a scientific experiment: first define the hypothesis, build the minimal test, measure key metrics, then learn from data and make decisions
- MVP Design and Execution - The core of designing a minimum viable product is identifying the most critical unvalidated assumption and validating it at the lowest cost
Key decisions and timeline
- 2001 Graduates from Yale University, Joins Silicon Valley Startup Scene - Failure is the best opportunity for learning; the key is to systematically distill reusable lessons from failures
- 2004 Co-founds IMVU Instant Messaging Virtual World - Spending enormous time building a product without validating assumptions is the most common and most expensive mistake in entrepreneurship
- 2007 IMVU Achieves Transformation and Growth Through Lean Methods - Data-driven rapid iteration is better at finding true product-market fit than large-scale perfect planning
Beliefs and mental models
- Belief 1 - Startups are not executing a known business plan but searching for a sustainable business model. Therefore, the core activity of entrepreneurship is not execution but learning — validating assumptions about customers, markets, and products through rapid experimentation.
- Belief 2 - A minimum viable product is not the worst possible product but the version that allows the maximum amount of validated learning with the least effort. Through MVP, entrepreneurs can quickly test whether the most critical assumptions hold before investing significant resources.
- Belief 3 - When experimental results indicate the current direction is not viable, pivoting — retaining validated learning while changing strategy — is the right choice. The ability to quickly identify pivot signals and decisively execute is one of the core capabilities of excellent entrepreneurs.
